摘要：NOVELTY - Multi performance hydrogel comprises regular internal three-dimensional network structure, and aperture size is 8-20 mu m. USE - Used as multi performance hydrogel. ADVANTAGE - The hydrogel: has 9100% elongation at break, 1.75 MPa bear pressure, more than 2000 water swelling rate. The method is easy to control. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing multi performance hydrogel, comprising using 0.1-2 g polystyrene-polyacrylic acid spherical polymer brush and water preparing 0.01-1 wt.% aqueous solution, taking 0.1-1 ml prepared aqueous solution, 0.2-2 ml acrylic acid, 0.3-2 ml water and 0.02-0.3 g photoinitiator, mixing in glass mold, carrying out ultrasound for 5-40 minutes, placing ultraviolet lamp and irradiating for 10-120 minutes to obtain the hydrogel.
